Abstract: PURPOSE:To stably control the delivery water temperature in accordance with the limit value and the load of an air conditioner by a method wherein the control value of a circulating water temperature is determined to every rotational frequency of a pump for a heat source apparatus. CONSTITUTION:Signals Sr, which represent the rotational frequencies of pumps P1 and P2 and are obtained from tacho-generators TG1 and TG2, are given to a factor converter FCV and, upon being converted to percentage, given to one input terminal of a low value selector LSE. On the other hand, a signal Si, which represents the return water temperature thetai, is sent together with the set value SPi of the return water temperature thetai to an operator PID1 and, after being subjected to PID (proportion, integration, differentiation) operation in order to be turned to the instruction value of a circulating water temperature theta0, given to the other input terminal of the low value selector LSE. Accordingly, the circulating water temperature can be controlled continuously, resulting in enabling to stably control the rotational frequencies of the pumps without the generation of misjudgement of the quantity of air conditioning load with respect to controlling, even under the condition that the valve opening of air conditioning load does not conform to the circulating water temperature.
